ORNAMENTING GLASS.

SPECIFICATION forming part of Letters Patent No. 632,008, dated August29, 1899.

Application filed November 21J l 898.

To a/ZZ whom, it may 0071007721:

Be it known that LOoRNELIUs BDOBPOLS, a citizen of the UnitedStates,residing at Berwyn, in the countyof Cook and State of'Illinois,have invented a newr anduseful Improvement in Ornamenting Glass, ofwhich the following is a specification.

My objectin the present invention has been to devise a method ofproducing sheets of stained or ornamental glass having portions of theirsurfaces raised above or sunken below the general plane of the sheet.These raised or depressed portions may form medallions or panels in thesheets or they may be nearly coextensive with the sheets.

In the practice of the invention I apply a design in color to the sheetor some portion thereof in some such manner as that set forth in myPatent Nofll, the paints used being such as are used in staining theglass for church-windows and embodying both ground and finishing colors.After the picture or` design has been thus applied to the glass I firethe same in the usual manner, except that the sheet of glass issupported While being fired upon a plate Which is cut out or recessedunder those portions of the sheet which it is desired shall be raised orsunken, so as to'allow such portions to sink into the recess. For thispurpose the plate may be out entirely away under the part which is to bebent, or it may be simply hollowed out, as preferred. The outline of thesunken or raised portion Will correspond with the outline of the recess.During the firing of the sheet whereby the colors are burned into theglass that portion of the sheet over the recess in the supporting-plateWill sink by reason of its own gravity into the recess and thus form theraised or sunken surface desired, one sideof the sheet being thus raisedand the reverse side being sunken. In this manner I avail myself of thesoftened condition of the glass produced by the heat by which the colorsare burned as a means of causing the bending of the glass and avoid thenecessity of subjecting the glass to a separate firing for the latterpurpose.

In the accompanying drawings I show at Figure l an elevation of a sheetembodying my invention; at Fig. 2, a section of the same,

Serial No. 696,999. (No specimens.)

and at Fig. 3 a section of the supporting-plate used during the iring.

In said draWings,A represents a plane sheet of glass, in the center ofwhich a picture or Aon the colors and unites them to the glass also sosoftens the glass as to cause that por-V tion of the sheet over therecess in the plate, and which in the case illustrated is the portion toWhich the design is applied, to stretch and fall by gravity into therecess, thereby bending such portion into a concave-convex form. Thesheet when removed from the oven and properly annealed will have beenbent in the manner shown in Figs. l and 2. The design may be appliedeither to the side which in the bending will be raised or to the sidewhich Will be sunken, according to the effect desired. The appearance ofthe design may be much heightened by thus bending the glass, as upon theconvex side especially a rich opalescent effect is produced.

I do not Wish, of course, to be limited to any particular shape, form,or outline in the bent portion of the sheet, nor to the bending of aportion only of the sheet, nor to the bending of any particular part ofthe sheet.

I clairn- 1. The process of producing ornamental glass, consisting inapplying the design in colors to the glass Without iring and thensimultaneously fusing the color and bending the glass by heat,substantially as specified. 2. The process of producing ornamentalglass, consisting in applying the design in colors to the glass withoutring and then simultaneously fusing the color and bending the glass byfiring the glass while it is supported upon its edges, substantially asspecilied.
